The main purpose of this paper is to establish, using the Littlewood-Paley-Stein theory (in particular, the Littlewood-Paley-Stein square functions), a Calderón-Torchinsky type theorem for the following Fourier multipliers on anisotropic Hardy spacesHp(ℝn;A) associated with expensive dilationA:Our main Theorem is the following: Assume thatm(ξ) is a function on ℝnsatisfyingwithThenTmis bounded fromHp(ℝn;A) toHp(ℝn;A) for all 0 <p≤ 1 andwhereA*denotes the transpose ofA. Here we haveusedthe notationsmj(ξ)=m(A*jξ)φ(ξ)and is a suitable cut-off function on ℝn, andWs(A*) is an anisotropic Sobolev space associated with expansive dilationA*on ℝn.
